Will the US Mobile Warp network work on a European iPhone 17 Pro that has a physical SIM tray?
You can likely get basic service on US Mobile by using a physical SIM card, but you may not get full 5G speeds. Unlocking your phone does not automatically make it technologically compatible with Verizon's network frequencies.
You did the right thing by checking your phone's compatibility before relying on it. While a physical SIM card bypasses the eSIM block for previously locked phones, you can test the service first to see if the speeds meet your needs.
You asked if the US Mobile Warp network will work on a European iPhone 17 Pro with a physical SIM tray. The provided documents do not state whether this specific model is compatible. They also do not confirm US Mobile's exact policy for international models or detail the hardware specifications of European iPhones regarding Verizon's 5G bands.
However, the Federal Communications Commission (FCC) confirms that unlocking a phone only removes the software lock. It does not make the phone technologically compatible with a new network. Phone companies use different frequencies to provide access.
Verizon (which powers US Mobile's Warp network) uses specific frequencies for its 5G service. This includes millimeter wave (mmWave) for high capacity and C-band for mid-band coverage. If your phone lacks the hardware to read these specific frequencies, it will not achieve full 5G performance on this network.
